B. Chloro fluoro carbon are suppose to main cause of ozone layer depletion
C. Ozone is produce in upper stratosphere by action of UV rays
D. Ozone is not responsible for green house effect

Answer

To determine which statement about ozone is wrong, we can analyze each option provided in the question.

**Step 1: Identify the statements about ozone.**
- Statement A: Ozone is an allotrope of oxygen with the molecular formula O3.
- Statement B: Ozone protects us from harmful UV rays of the sun.
- Statement C: Ozone is present in the upper stratosphere.
- Statement D: Ozone is a greenhouse gas and is responsible for the greenhouse effect.

**Step 2: Evaluate each statement.**
- **Statement A**: This statement is correct. Ozone (O3) is indeed an allotrope of oxygen.
- **Statement B**: This statement is also correct. Ozone absorbs and protects us from harmful UV radiation from the sun.
- **Statement C**: This statement is correct as well. Ozone is primarily found in the upper stratosphere of the Earth's atmosphere.
- **Statement D**: This statement is incorrect. While ozone does have greenhouse properties, it is not primarily responsible for the greenhouse effect in the same way that carbon dioxide and methane are. In fact, ozone in the stratosphere is beneficial as it protects against UV radiation, while ground-level ozone can contribute to air pollution and has different effects.

**Step 3: Conclusion**
The wrong statement among the options provided is **Statement D**: "Ozone is a greenhouse gas and is responsible for the greenhouse effect."

**Final Answer: Statement D is wrong.**
